How do pesticides help the environment?
Modern crop protection practices support increased productivity on existing farmland, so alleviating pressure on uncultivated areas which provide important habitats for wildlife such as birds, bees and other insects.
How do pesticides harm humans and the environment?
Environmental Effects Chemical pesticides are known to pollute the environment. too much movement can transfer a pesticide away from the target pest. This can lead to reduced pest control, contamination of surface water and groundwater and injury of non-target species, including humans.”
What are the harmful effects of pesticides on the environment?
Pesticides can accumulate in bodies of water to levels that kill off zooplankton, the main source of food for young fish. Pesticides can also kill off insects on which some fish feed, causing the fish to travel farther in search of food and exposing them to greater risk from predators.
How does fertilizer affect the environment?
When the excess nutrients from all the fertilizer we use runs off into our waterways, they cause algae blooms sometimes big enough to make waterways impassable. When the algae die, they sink to the bottom and decompose in a process that removes oxygen from the water.
What are disadvantages of fertilizers?

- They are expensive.
- The ingredients in the fertilizers are toxic to the skin and respiratory system.
- Excessive use of fertilizers damages the plants and reduces soil fertility.
- Leaching occurs and the fertilizers reach the rivers causing eutrophication.

Why are fertilizers bad for the soil?
Though chemical fertilizers increase crop production; their overuse has hardened the soil, decreased fertility, strengthened pesticides, polluted air and water, and released greenhouse gases, thereby bringing hazards to human health and environment as well.
Is fertilizers good for soil?
Fertilisers work by providing essential nutrients to developing flowers, trees and veg, as a kind of multi-vitamin or meal replacement for the plant world. Many fertilisers also improve the way the soil works by helping it to retain water better and allowing air to flow freely, which is good for roots.
Why do farmers add fertilizers to the soil?
Manures and fertilizers help in conserving and enriching the fertility of the soil. By growing plants again and again on the same soil, the soil becomes deficient in nutrients. Thus it is necessary to replenish the soil with these nutrients. That’s why farmers add manures and fertilizers to the field.
