Environmental Issues

Polymers are often made from crude oil distillates that cannot be turned in to gasoline. We pay for crude oil, what sense does it make to put it back in the ground where it serves no useful purpose, and is so stable it will not become crude oil again?

Additionally, some polymers leach compounds into the ground water, which can become a problem for future generations (some we cannot foresee, of course).

The validity of the above answers are questionable but it is true that polymers are very stable. It is not known how long plastic will remain in a landfill so it will continue to accumulate. Some envision a world where there are large mountains of plastic trash. I hope that world never comes.

Gypsum is composed primarily of calcium sulfate dihydrate. It contains calcium, sulfur, and oxygen atoms arranged in a specific crystal structure. No other minerals are present in significant amounts in gypsum.

Current environmental issues, such as climate change and air pollution, are driving the need for increased use of renewable energy sources to reduce greenhouse gas emissions and improve air quality. These issues are creating a sense of urgency for governments and businesses to invest in and accelerate the adoption of renewable energy technologies. Additionally, natural disasters, like hurricanes and wildfires, are highlighting the vulnerability of traditional energy systems and the benefits of more resilient renewable energy solutions.

Some safety issues for humans around panthers include attacks if they feel threatened or cornered, especially while defending their territory or young. Human-wildlife conflicts can arise if panthers are attracted to urban areas by food sources like pets or livestock. It's important to avoid approaching or feeding panthers and to be aware of your surroundings when in panther habitat.

It is renewable because you can always raise an object or raise yourself and gain gravitational potential energy. You cannot run out of gravitational potential energy and even now you have some of the the energy because gravity is always pulling you. It is just a matter of how much gravitational potential energy you have. Go on the top Mt. Everest and you will have more gravitational potential energy than most of the people in the world.

Its a Noun, and here is the definition:

A fossil formed when an animal, plant, or other organism dies and is covered by sediment, it flesh decays and bones deteriorate due to chemical reactions, and a cavity remains below the ground surface; the cavity's interior surface is an 'impression in the general form of the original organism's exterior surface.

The wind electricity work because of the wind mill, wind mill makes wind energy.

because:

- made from crude oil

-non-renewable resources

- litter

- not biodegradable

- use energy to make

- when burned or biodegraded carbon dioxide is released

- to encourage customers to reuse bags / use their own bags.

Forests are a natural resource that can be used and replaced over time. Through sustainable management practices like reforestation and afforestation, trees can be replanted and replenished, allowing the forest to continue providing wood, oxygen, and habitat for wildlife.

Probably not. If we recycled everything possible so we had no trash at all. We still would use energy (from burning fossil fuels) to heat our homes, cook and produce our food and move about.

Our contribution to global warming is mostly CO2 Carbon dioxide. We burn fossil fuels (coal, oil and natural gas). We eat carbon in the form of food, breathe oxygen and with digestion produce CO2 and Methane.

Both being contributors to warming. Methane being 20 times more destructive than CO2.

Methane is also produced when organic material like grass clippings rot. It is the major component of natural gas.

More people on the planet requires more food and heat for warmth.

But the Earth has a weapon to balance things out. Vegetation consumes CO2 and produces oxygen. Plankton in the oceans produce the most. Plankton is also the most vulnerable to destruction by warm water and harmful cosmic rays. The polar oceans produce more plankton than the warm waters on both sides of the equator. That is one reason why there are more fish there.

There are experts that dispute Global Warming is caused by humans. The evidence says the opposite. We are warming faster than ever before. If you check the deniers' trail you will find that most if not all are recipients of money from the coal industry which has the most to lose by being replaced with green energy.

Besides recycling, the best thing we can do is plant trees, millions of them. Most of the US except the plains and deserts were covered with huge forests before the Europeans settled the land. They cut the trees, used the timber for buildings and turned the forests into farm land.

There are plenty of places we can replant indigenous trees. Any place the sun shines where a tree won't be a hazard and has decent soil will do. Not only will a tree remove perhaps tons of CO2 in its lifetime but will produce more oxygen and keep the space underneath the branches cooler.

The country has been experiencing an extremely hot weather recently and even it rained on the Chap Goh Meh, the rains poured with pollutants and it did not help much in raising dam's water level. The water level has reached a record low

A cast fossil is formed when a mold fossil is filled in with minerals or sediments, creating a replica of the original organism. The mold is created when an organism decays or is buried in sediment, leaving an impression behind. Cast fossils can provide valuable information about the shape and structure of the original organism.

The difference from marine Biology and marine zoology is that marine biology is the study of animal and invertebrates instincts, anatomy, or lifestyle. While marine zoology is ultimately all about animals in general.

Human activities have damaged mangrove ecosystems through deforestation for agriculture, urban development, and aquaculture. Pollution from industrial activities, agriculture, and sewage has also negatively impacted mangroves by degrading water quality. Additionally, overharvesting of resources such as timber and shrimp can disrupt the balance of the ecosystem.

No they aren't! Although cats cannot see colours like us, they are not fully colourblind. They see the world in blues and greens but cannot distinguish the different shades of red.

They can see other a few other colours as well, just not too brightly. Lion's only see in black and white.

Many natural disasters have occurred in the geographical area known as the "Ring of Fire". These include: hurricanes, typhoons, cyclones, earthquakes, volcanoes, landslides, epidemics, famines and heat waves.

The world can produce less carbon dioxide by transitioning to renewable energy sources such as solar, wind, and hydroelectric power, promoting energy efficiency in buildings and transportation, implementing policies to reduce deforestation and promote reforestation, and encouraging sustainable agricultural practices. Additionally, investing in carbon capture and storage technologies can help to reduce carbon dioxide emissions.

Chernozem (from Russian чернозём, black soil), also known as "black land" or "black earth", is a black-coloured soil containing a very high percentage of humus - 3% to 15%, and high percentages of phosphoric acids, phosphorus and ammonia. Chernozem is very fertile and produces a high agricultural yield.

A rain gauge needs to be positioned out of the shelter of houses and away from trees. Ideally, it should be placed on a post in the middle of a garden, where there are no trees or tall bushes nearby.

In 2100 water levels will rise by three feet. Any city below three feet of sea level will flood. Many cities will flood because there are many cities below sea level. Not everybody will be flooded. Much of the world's fresh water comes from mountain glaciers. So if those glaciers melt people will run out of fresh water and people will die especially the people that live in Asia.

Thuban has a spectral class of A0. Similar to Vega in temperature and spectrum, but more powerful and more massive.

Thuban is no longer a main sequence star, it has used up all the hydrogen in its core and is now fusing helium. That makes it a white giant star, being 250 times more powerful than our Sun. It's about 300 light years from us.

The sun is directly overhead at the summer solstice at the Tropic of Cancer (23.5oN). This is as the most northernly latitude which has the sun directly overhead at any time of the year. A similar case happen at the winter solstice at the Tropic of Capricorn (23.5oS).

They proudly are called Environmentalists.
