1. ozone depletion - 2. Higher levels of ultraviolet rays reach Earth, affecting humans, plants. and animals.

2. climate change - 4. It adversely affects the living conditions of humans, plants, and animals

3. increased human population - 3. More people are living in poverty, deprived of the basic needs of food, water, shelter, and clothing.

4. declining fish population - 1. Several fish species are extinct or moving toward extinction.

Explanation:

1) Ozone layer is one of the most important layers present in stratosphere that restricts the entry of harmful ultraviolet radiation to reach earth surface. Depletion in ozone layer due to global warming allows the entry of ultraviolet rays at earth surface and can affect living organisms. Ultraviolet radiation can cause skin cancer, eye cataracts, and genetic damage in humans; UV rays affects the physiological and developmental processes of plants and animals can also face several skin diseases and genetic disorders.

2) climate change is one of the major environmental issues in todays era. climate change is the result of increasing pollution which causes global warming. Due to climate change living conditions of humans, plants, and animals aer adversly affected. climate cange is supporting increase in temperature that is mking living life difficult to live. Season chain is also badly affected by climate change and water resources are getting over due to high temperature (evaporation).

3) Increased human population has adverse effects in the surroundings. Increased population is responsible for decrease in resources, less employment and poverty et-cetra. Due to poverty and less employment people are deprived from their basic needs such as food and clothes.

4) Declining fish population can expand to food web and affects the population of algae, insects, bacteria and other species. so, decline in fish population allows other fishes to get extinct due to changes in food web.

Hnce, the correct match is: 1-2, 2-4, 3-3 and 4-1.
