Using pesticides for a long time can have negative impacts on the environment such as soil degradation, water contamination, and harming non-target species. It is not considered sustainable in the long term as it can disrupt ecosystems and compromise biodiversity. Adopting integrated pest management strategies that minimize pesticide use and promote sustainable agricultural practices is a more environmentally friendly approach.

What are persistent pesticides?
Persistent pesticides are chemicals that remain in the environment and can accumulate over time in soil, water, and organisms. These pesticides do not easily degrade, which can lead to long-lasting environmental and health impacts. Examples include organochlorine pesticides like DDT and chlordane.
How do pesticides contaminate groundwater?
Pesticides can contaminate groundwater when they are applied to fields and leach through the soil into the groundwater. Rainfall or irrigation can help move the pesticides deeper into the ground where they can reach the groundwater. Once in the groundwater, pesticides can persist for a long time and potentially impact drinking water sources.
What is the difference between old and modern pesticides?
Old pesticides, such as DDT, were typically broad-spectrum chemicals that remained in the environment for long periods of time, causing harm to non-target species and the ecosystem. Modern pesticides are designed to be more specific in their target, with reduced persistence in the environment and lower toxicity to non-target organisms. Additionally, modern pesticides often undergo more rigorous testing for safety and environmental impact before being approved for use.
Why do pesticides become ineffective over time?
Pesticides can become ineffective over time due to the development of resistance in target pests, where they evolve to withstand the pesticide's effects. Additionally, repeated use of the same pesticide can lead to the buildup of residues in the environment, reducing its effectiveness. Environmental factors like temperature, humidity, and soil type can also affect the breakdown and efficacy of pesticides.
Why are chemical pesticides dangerous to living things?
It is because pesticides contain dangerous substance that can harm living things. Example of negative effects is 'Eutrophication'. This process is the when pesticides are used and promotes the growth of algae in a water source and it makes underwater plants cannot do their photosynthesis. Fishes will die due to lack of oxygen and lot of unabsorbed carbon dioxide that are dissolved in water.
What are persistent pesticides?
Persistent pesticides are chemicals that remain in the environment and can accumulate over time in soil, water, and organisms. These pesticides do not easily degrade, which can lead to long-lasting environmental and health impacts. Examples include organochlorine pesticides like DDT and chlordane.
Is nuclear power sustainable?
For a long time to come, compared with oil and gas
How do pesticides contaminate groundwater?
Pesticides can contaminate groundwater when they are applied to fields and leach through the soil into the groundwater. Rainfall or irrigation can help move the pesticides deeper into the ground where they can reach the groundwater. Once in the groundwater, pesticides can persist for a long time and potentially impact drinking water sources.
When were organic foods first made?
Growing food organically (without using synthetic fertilizers and pesticides) is the way foods were grown from the beginning of time until synthetic pesticides and fertilizers were created, and growing organically is still being done today.
How do persistent and non-persistent pesticides differ?
Non-persistent pesticides are compounds that break down quickly in the environment. Several different classes of pesticides make up this group: • Cholinesterase-inhibiting pesticides, which includes the organophosphates and carbamates • Chlorinated phenols • Herbicides • Pyrethroids • Fungicides • Repellents Non-persistent pesticides became widely used after persistent organochlorine pesticides were banned from manufacture and use in the United States in the 1970s. Non-persistent pesticides are less harmful to the environment because they do not build up but they have to be applied more often to households and crops to be effective.
Which type of pesticide has the longest residence time in the environment?
Organochlorine pesticides, such as DDT, have been known to have a long residence time in the environment. These compounds are resistant to breaking down and can persist in soil, water, and organisms for many years, causing potential harm to ecosystems and human health.
Can you use pesticides any time of the year?
Yes.
What does sustainable meen?
Sustainability is the potential for something to continue surviving is a healthy or successful way over a long period of time.
What is the meaning of lasting impression?
it's like a sustainable impression. It's an impact on a person which will stay a long time in his mind.
What are the benefits of using stainless steel cutlery in the kitchen?
Stainless steel cutlery is durable, resistant to rust and corrosion, easy to clean, and does not react with food. It also maintains its appearance over time and is a sustainable choice due to its long lifespan.
