A) how to control over population​

Answer 1

Explanation:

We Indians treat soil as our mother but not when it comes to preserving it. The mainspring for land pollution is oil refineries, deforestation, garbage and waste, mining sources and agricultural sources. In order to subdue land pollution, people should be educated and made aware about the harmful effects of littering. We should discuss with friends and family and talk about it. Buying of biodegradable products is quintessential. We should switch to organic foods that are grown without pesticides. Personal litter should be disposed properly. We can separate household waste at home for recycling. The best way to curb land pollution is following simple three R’s, they are Reduce waste, Re-use things and Recycle things.

Under the pollution control approach, attempts to protect the environment have especially relied on isolating contaminants from the environment and using end-of-pipe filters and scrubbers. These solutions have tended to focus on media-specific environmental quality objectives or emission limits, and have been primarily directed at point source discharges into specific environmental media (air, water, soil). As environmental pollution control technologies have become more sophisticated and more expensive, there has been a growing interest in ways to incorporate prevention in the design of industrial processes – with the objective of eliminating harmful environmental effects while promoting the competitiveness of industries. Among the benefits of pollution prevention approaches, clean technologies and toxic use reduction is the potential for eliminating worker exposure to health risks.

Let our future generation see the exploding palms, clear skies, elegant waves, etc. In short let them enjoy the mesmerizing beauty, the elegance of nature and live in a safe, healthy and uncontaminated environment.

Answer 2

Answer:

Population control can be influenced by a variety of factors. Humans can greatly influence the size of animal populations they directly interact with. It is, for example, relatively common (and sometimes even a legal requirement) to spay or neuter dogs. Spaying – removing the ovaries and uterus of a female animal – medical term = ovariohysterectomy. Neutering - removing the testes of a male animal – medical term = orchiectomy. Various humans activities (e.g. hunting, farming, fishing, industrialization, and urbanization) all impact various animal populations.

Population control may involve culling, translocation, or manipulation of the reproductive capability. The growth of a population may be limited by environmental factors such as food supply or predation. The main biotic factors that affect population growth include:
