Why birds decrease

About the decline in the birds population for the last 20-30 years, what’s the reason for it ?. Ornithologist agreed that there are no conclusive scientific evidence stating that cell phone towers are the reason behind the decline. Which means there are larger forces at play here causing this decline in birds population. The biggest cause among them is agriculture! Experts believe growth in agriculture, has led to an increase in use of pesticides, which in turn has led to decline in insect population. Since insects are the food for birds, birds cannot feed properly, hence their population is also declining Agriculture is said to be one of the major reasons. This reasons not only in India, but all over the world, the bird population has started declining. Agriculture invasive species are the main factor. The other obvious reasone are urbanization, deforestation, climate change, and pollution is another inportant factor here. Which I fell, specfically in our country is very valid. We can see that nowhere among these threats, call phone towere are specifically mentioned. Wildlife conservation and bird conservation are very important environmental issues. It would have been scientifically correct. It the real message to audience. That not to use excessive pesticides and to promote organic farming. This could have had an actual on the falling bird population,in June 2018 more than 200 scientists from around the world wrote an petition that a specific family of pesticides calls neonicotinoids should be banned beacuse this family of pesticide is adversely affecting the biodiversity and bird population. Now this has been scientifically proven as well. Many researchers have shown direct evidence for it.
