If bees become extinct, humans will also become extinct at some point.

In the 1950s, American scientists found that the number of eggs laid by some species of eagle, hawk, and vulture was decreasing. They continued to research what was the reason for this.

When scientists took all the eggs of these birds and examined them, they found many startling information. Some eggs had thin shells and some had no shells at all. This revealed that the embryo of the egg was in an unsafe condition.

It has been revealed that the number of eggs laid by large birds is decreasing and the egg shells are thin due to the use of the chemical DDT and pesticides in agriculture because when pesticides are sprayed in the fields, it affects insects, mice, frogs, etc., which are preyed upon by large birds. Due to this, large birds are affected and their natural characteristics are reduced. At the same time, small birds are not affected much by ordinary insecticides. The eggs they lay are the same as ever. Why this is so has remained a mystery to scientists.

Pesticides and chemicals sprayed on the fields do not completely lose their properties, which are washed away during floods and end up in the sea. The effects of these drugs are also seen in Antarctic penguins.

  It has yet to be fully studied why it affects the body even in humans and thus whether it affects humans. The US and some other countries have banned the use of chemical pesticides. However, in some countries, pesticides are still used in large quantities, which can affect all species of birds. All migratory native birds are likely to be affected by pesticides used in a country. So it is better to avoid using chemical pesticides.

If we protect nature, nature will protect us. It cannot be ignored that birds and insects play a major role in agriculture. Because among insects there are also beneficial insects and it is because of these useful insects that agriculture flourishes and yields increase. So taking insects as a whole is dangerous.

Hunting all the birds will increase the number of insects, and killing all the insects will decrease the number of birds. So if we preserve the balance of nature, nature will keep man in balance. 

Albert Einstein said that if there were no bees, the world would perish in a few days, and the reason is that bees are the cause of most of the pollination in the world. So if bees die out, pollination will drop by 90 per cent.

 This will reduce the formation of new types of plants, and if there are no plants, the proper amount of oxygen will not be available to humans. This is why we need to protect nature.
