Daniel Blechynden

Contributing Writer

Albany, Western Australia

Daniel grew up on a small farm on the south coast of Western Australia, and as such, have always had a close connection with nature. Currently, he spends his time travelling the world and discovering new places, cultures, and languages.

He is an ocean fanatic – some of his closer friends wonder if he is half fish. He loves diving, surfing, underwater photography, and basically any activity involving salt water. He also enjoys playing Australian football with his current team, the Paris Cockerels.

Why do we bother?

Many environmental challenges present today are caused directly or indirectly by human actions. Deforestation, land degradation, water pollution, resource depletion, endangered species and global warming are just a few problems that affect our environment.

Why protect the environment?

The environment (the Earth) is the place we call home. It is where we live, breathe, eat and raise our children. Our entire life support system depends on the well-being of all of the species living on this planet. Thus, it is our responsibility to ensure that future generations enjoy the right to a healthy environment, in the same way like we have it now.

A first step in addressing environmental issues is raising awareness. Our goal is to provide education and raise awareness on environmental issues and help initiate the change in attitudes and behaviors towards a more sustainable lifestyle where Nature conservation becomes a main priority in our lives.

We are constantly researching topics on environmental issues, and adding new content to this site on a daily basis. If you also think the cause we are fighting for it’s worth it, then join us! We are a team of young people motivated to work hard to protect the environment and conserve natural resources and you are welcomed to take part of our team. Some of the ways you can help:
