alarmed about the mysteriously disappearing bees in the United States during 2006, when healthy bees were leaving their colonies in search of pollen and nectar, however never returning back to their hives. From then, this large ongoing decline in the bee population has been continuously leading to different threats, having a great impact on social/society issues, raising concerns relating to possible risks of global food security, and on the economy, where agriculture takes up a large portion of the
and cultural values for people. Birds are important for humans due to many reasons. Birds provide us food, medicine, fertilizers and also bring about pollinations. Birds are a part of the food chain. Birds also perform vital ecological role, besides their economical role. They are critical links within the vast food chains and webs that exist in the ecosystem. The economic importance of birds can be studied into two parts – A) Beneficial effect
than 350 mm of rainfall. Causes and Dangers: Agriculture increase and misuse is one of the central causes of desertification. Agricultural practices require the use and often the drying up of rivers. While water overuse is fundamental to the creation of drought conditions, the deforestation and soil erosion could be considered far more detrimental. To create agricultural surfaces, land must be cleared of existing vegetation. As roots bond soils and create micro bacterial gums, their loss has significant
It is an ecosystem process that has evolved over millions of years to benefit both flowering plants and pollinators. Pollination is critical for food production and human livelihood and directly links wild ecosystem with agricultural production system. It plays an important role both in our survival and the existence of nearly all ecosystems on earth. Many ecosystems, including many agro-ecosystems, depend on pollinator diversity
and also bring about pollinations. They are important because they are a part of the food chain. Birds are also important because they help spread seeds around and thus help with the planting process. Birds also perform vital ecological role, besides their economical role. They are critical links within the fast food chains and webs that exist in the ecosystem. The economic importance of birds can be studied into two parts – A) Beneficial effect B) Harmful effect.
declining at a rate 10,000 times faster than normal according to a census of the world’s species (Dugan). What is causing such a rapid increase in extinction is unknown however there is one thing that is indisputable: human interference is playing a direct role. Poaching is the illegal hunting, killing or capturing of animals. Poachers sell the animals as pets, foods, and fur. During the 1960s jaguars, leopards and tigers were poached for fur and meat. The animals organs and meat were then sold as aphrodisiac
