How do raccoons use living and nonliving things?
the raccoon eats the trash and it helps poullution
What spreads more poullution row boats or cars?
CAR SPREADS more pollution.
What are boogars made of?
The correct spelling is boogers. Boogers are actually built up ollution in your nose. That's why pollution is also very bad because it clings to the hairs or fibers in your nose and builds till it slowly clumps up. It gets it green color by the way you breath because if you breath in it pull pollution with it and then when you breath out it pushes out, like your washing the poullution back and back again, and then it dries and hardens.
What causes air poullution?
Population causes air pollution is lots of ways. If there was one person in the world, he or she could make pretty much as much mess as he or she wanted and the world would absorb it or fix it through natural processes, but when there are nearly 7 billion people, the small amount of pollution each person makes adds up to an amount of pollution that changes the whole environment. The population of the world has increased enormously in the last 100 years and the need for energy and products has increased as the standard of living has improved. This has meant that we use more energy and have more products, which require energy to make. More people need more transport, more heating, cooling and more food. Industry often causes air pollution, although efforts are being made to reduce this, cars, heating andair conditioning are all energy intensive and cause pollution. Even though things like cars use less fuel to get you the same distance they might have 50 years ago, there are millions more cars and they are not a million times more efficient!Even things like food require energy and this causes pollution in its production, processing and transport, not to mention the increasing demand for meat, which means there is a much bigger population of herbivores than there was, and they produce methane gas as they digest plants. Methane is a particularly polluting greenhouse gas that traps heat and causes global warming. Methane is also produced in large quantities in land fill sites and sewage works where our waste is disposed of.Food, raw materials and products are often transported across the world which also uses up energy and causes pollution.For years there have been people living in some parts of the world that has used most of the world's resources, other people have been living with a much closer relationship with their environment. These people are referred to as people living in undeveloped countries. As countries 'develop' their population need all the things 'developed', energy greedy countries have, like cars, fridges, air conditioning etc, which means that not only has the population exploded, but the individual energy requirement of each person has too.Making energy and products is usually cheaper where simple coal fired power stations are made or where factories do not have expensive waste treatment on chimneys, which means that developing countries can cause more air pollution than in Europe or North America. This keeps cost down in the developing countries and enables them to meet their increasing needs. It also means that they can often make products cheaper than in parts of the world where there are stricter air pollution laws. People in developed countries often don't care how something is made. They just want it as cheaply as possible. This means that we often buy things made in a very polluting way. When developed countries improved emission standards, often the manufacturing just relocated to another part of the world where there were less or no restrictions. Ultimately we all share the same air.There have been big steps for manufacturers to reduce pollution in their products and the manufacture of their products but the need to have so many more products offsets these improvements. Although the rate of increase has slightly decreased, it is still increasing and this is a serious problem that will mean countries will have to put the environment before their economic growth, something no-one is keen to do.Even green energy products like solar panels and wind turbines take a lot of energy and materials (which takes energy) to make and the people making them use energy to live whilst they make them, which means there are very few short term solutions. Even recycling products often uses more energy than making the product from scratch once collecting, sorting and processing are taken into account.
