Explain what is ecological conservation and conservation of the environment. What can you do to conserve the environment? Why do
den301095 [7]

Answer:

Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.

-These are some examples of how we can conserve the environment:

Recycle your rubbish and participate in or help organize recycling campaigns.

Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).

Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).

Swap toys, movies, and books instead of buying new ones.

Donate, recycle, and repair electronic devices (see how here).

Use less water when brushing teeth, taking a shower, or washing the dishes.

Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.

Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.

Use less paper by not printing unnecessary things and reading e-books.

Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.

Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.

Do not waste food and try to buy food that is grown locally and in season.

Hope this helps:)
