Environmental Benefit

-->> Quality of topsoil
Use of agrochemicals over time reduces the quality of the topsoil, which is  vital for plant growth. As a result, farmers have to use more and more chemical fertiliser over time to achieve the same results. The planting of short-term cash crops on farmland, or land cleared from the jungle, often leaches so many of the nutrients from the soil, that the land cannot be used again for another crop. In the case of jungle clearance, topsoil washes away, and the land remains
deforested for a long time.

Sustainability of organic farming systems involves soil development and conservation as a major aspect. Use of manure, compost and vegetable matter improves the soil structure and, consequently increase soil quality rather than the reduction of soil quality often associated with conventional farming. Over time the productivity of the soil increases the output or harvest.

-->> Cleaner water
Agrochemicals drain through the land and enter rivers and other water into supplies, eventually leading the oceans. This means levels of agro-chemical in drinking water, and harmful effect on wildlife especially fish, many miles away from the farming area.

On the other hand non-use of chemicals in organic agriculture means no contamination of drinking water rivers, lakes and oceans from chemicals.

-->> Increased biodiversity
Biodiversity on farms where agro-chemicals are used is generally diminished. Many species of wild plants, animals, insects and birds are affected by the chemical use. This can be seen in Europe with the decline in numbers of songbirds, wild flowers in hedgerows and fields, and native animal species. The same is true all over the
world.

On the other hand bio diversity increases on organic farms. Native flora and fauna can re-establish population.
