a. Environmental problems: What are they?

b. Environmental protection: How important is it?

c. Environmental solutions: How practical are they?

The environment we live in is facing many serious problems. We need to be aware of these problems so that we can find ways to protect nature.

A. Global warming is the rise in the average temperature of the earth's atmosphere. It is one of the biggest issues facing humans today. It can have serious consequences such as rising sea levels, polar ice melting, and extreme weather events like floods or heatwaves.

B. Another environmental problem is the cutting and clearing of natural forests. The loss of forests can have a negative impact on the environment. It can damage the natural habitats of many animals and put wildlife in danger. It can also destroy the natural soil and lead to climate change.

C. Air pollution is also a serious problem. It is mainly caused by waste gases that come out of vehicles, machines, or factories. When these harmful gases combine with the water in the air, they come down as rain or snow, which can damage all forms of life. In addition, this problem leads to global warming and climate change. It is also a major cause of respiratory diseases or even lung cancer.

D. Around the world, the number of endangered animals is rising. Many of them disappear because of pollution and climate change. In addition, humans illegally hunt and kill animals, and catch too many fish at once. This is upsetting the natural balance of ecosystems, which can be harmful to all living and non-living things.

The more people travel, the bigger impact they may have on the environment. How can we reduce it while travelling? Here are some advice.

Reduce your carbon footprint while travelling. Since flying produces more carbon footprint than any other means of transport, you should only fly when the trip is long. During the trip, you should walk, cycle or use public transport as much as you can. This not only helps to keep the environment clean, but also allows you to enjoy the beauty of nature and interact with local people. 

Choose eco-friendly activities that benefit animals and the ecosystem. Avoid activities that allow you to touch or ride animals because they disturb their natural patterns and attract many people. Instead, visit wildlife parks or organic farms. These will help you understand and respect the nature more and stop doing things that harm the environment.

Environmental Impact of Tourism

Although tourism is often called 'the smokeless industry', or an environmentally-friendly industry, it can actually damage nature. However, different kinds of tourism may have different effects on the environment.

• Mass tourism is a kind of tourism which involves tens of thousands of people crowding the same places at the same time of year. It often has a lot of negative impact on the local area, such as litter from tourists and pollution from traffic.

• Ecotourism provides tourists with opportunities to explore nature, and at the same time helps protect the environment and educates travellers on local environmental issues. It also promotes tourists' respect for local communities.

• Sustainable tourism involves not only environmental protection and cultural respect, but also efforts to keep profits local. It often refers to actions of the tourist industry as a whole.

• Responsible tourism encourages tourists to be more than visitors. Responsible tourists should not only be aware of their role, but also take part in protecting the environment, culture and improving the profits for local people. Responsible tourism often relates to specific actions of individuals, businesses, and communities.

EARTH HOUR

Earth Hour is a global event organised by the World Wide Fund for Nature (WWF). Held every year, it encourages people and businesses to turn off their lights and other unnecessary electrical devices for one hour from 8:30 p.m. to 9:30 p.m. on the last Saturday of March. Earth Hour was started as a lights-out event in Sydney, Australia, in 2007. Since then, it has grown to become an international movement for the environment, happening in more than 7,000 cities and towns across 187 countries and territories.

Earth Hour has created a positive environmental impact. It shows the public support for protecting the environment and saving the planet. It also draws attention to climate change and global energy issues, and promotes green activities worldwide.

Viet Nam joined the event in 2009 and has been an active and keen supporter since then. Besides switching off lights, people can take part in a number of activities to raise awareness of environmental problems and call for action for climate, people and nature.
