Answer: Biodiversity loss
Explanation:
The biodiversity can be defined as the variety of life forms on earth or any other region. The forests are rich sources of biodiversity. The hunting, poaching, animal trafficking, and other ill-legal related human activities are like to reduce the species richness in forests. As many species are dependent upon other species for food, mate and other requirements for completing the life cycle thus the well-being of the forests will get deteriorated by the loss of biodiversity.
Answer:
Polygenic inheritance
Explanation:
Polygenic inheritance occurs when a genetic trait is regulated by more than one genes. All the alleles of these genes together determine the phenotype of the organism for the polygenic trait. Here, the phenotype is regulated by the total number of dominant alleles for all the genes that regulate a polygene trait.
For example, human skin color is a polygenic trait. The final phenotype depends on the total number of dominant alleles of all the genes that regulate the skin color in human.

Ozone is formed by the reaction of of nitrous oxides and reactive organic substance catalyzed by sunlight. This is a photochemical reaction provided with ozone forming compounds and sunlight.
Acid rain is defined as nitrous(NO2) and sulfurous (SO2) compounds enter the atmosphere as smog thereby precipitating as acid rain. This is detrimental in the environment as well as in agriculture.
Global warming is precipitated by the burning of fossil fuels that increases carbon dioxide, a greenhouse gas that traps heat, in the atmosphere. The greenhouse effect is the main principle behind global warming.
Ocean acidification is when excessive carbon dioxide is dissolved in the oceans as carbonic acid thereby increasing the pH of the ocean. Increases in the pH of the ocean can affect the living conditions as well as industrial conditions near it.
Groundwater pollution is defined as contaminating the groundwater with the runoff from industrial agriculture including organic and inorganic wastes as well as infectious and nuclear wastes.
Algae blooms or algal blooms are precipitated by eutrophication or the increase in nutrients in water such as nitrogenous compounds and phosphorus from fertilizers. Eutrophication of water precipitates the abnormally high growth rate of algae.
Ozone layer destruction is associated with CFCs such as Freon and aerosols as these compounds neutralize and destroy ozone. These compounds form free radicals that convert ozone (O3) to oxygen (O2) thereby reducing its capability to protect the earth from UV radiation.
Deforestation is primarily caused by urbanization (cutting down trees to provide empty land in building structures) and industrial farming (converting forests into agricultural lands for farming).
