Environmentalism is an integration of the ideology and philosophy of protecting the health of the environment and the social movement resulting from it. Issues such as conservation, preservation, ecosystem restoration, and improvement of the natural environment are foremost on the agenda of environmentalists. Concerns and threats involving the Earth's biodiversity and ecology feature at the top of the list.

To be an environmentalist, follow the simple steps given below.

Discover what you are passionate about and do some research. There are a variety of environmental issues that will pique your interest. Protection of endangered species, reducing greenhouse gas emissions, avoiding wastage of natural resources, restoration of age-old landscapes, protecting forests, and encouraging recycling are some of the causes environmentalists support. Learning about environmental issues in your own locality, and taking a part in solving them, is a good way to get involved.

Take measure of your talents. Are you an extrovert and like to communicate verbally with people? Are you introverted and more inclined towards writing than to speaking? Do you like to communicate and spread your thoughts in words through correspondences? Are you someone who likes being out in nature? Can you play an instrument, sing, bake, paint or juggle? Your unique talents can contribute to bringing attention to, and raising funds for, environmental efforts. Consider getting involved in events, fundraisers and campaigns for conservation issues.

Get yourself acquainted with how the Earth works and how human activities are affecting it. To make sense out of the multitude of environmental issues and the science behind it, read magazines, books and articles, watch documentaries, and browse websites relating to nature. Share what you learn with family, friends, coworkers and associates. Use social media to spread the word on environmental issues.

Get in touch with other like-minded people or experts in the field. Getting connected with people, especially experts on the environment, is an important step on the way to becoming an environmentalist. Conduct searches on the web for people and organizations who share your thoughts and concerns. Join organizations, groups, websites and social media channels that promote your cause – or create your own. Learn from the experts and help make a bigger impact by joining forces with other people, groups and nonprofits who share your passion for environmentalism.

Pick up litter wherever you go and whenever you can. Litter not only dirties roads, parks and public spaces, it also pollutes the environment. It harms wildlife that comes into contact with it. You can pickup litter on your own in your spare time, or join or organize groups to clean up large areas.

Visit places like wildlife sanctuaries, nature preserves, and parks. Support their efforts. Volunteer. Enjoy the natural beauty of these places, observe animals and their behavior, and encourage others to do the same. Communicate to people in your social circles why these protected places are important.

Grow native plants in your backyard. Invasive species wreak havoc on ecosystems. Native plants are better adapted to the area where you live and need minimum caring. They are less vulnerable to pests and will benefit birds, insects and other wildlife endemic to your locality.

The more trees you plant the more you help the environment. Trees absorb harmful CO2, prevent their emission and alleviate global warming. They provide food and shelter for wild animals. Plant trees on your property, and help plant trees in your community.

Consuming organic food and using organic gardening methods contributes towards a safer, healthier environment. Minimizing the use of pesticides and fertilizers stimulates beneficial soil organisms and results in less polluted waste-water flowing out of your garden. Moreover, it creates a much healthier environment for wildlife, your children and your companion animals.

Reduce, Reuse, Recycle, Rethink. Reduce the amount of materials you use, which reduces the amount of waste you create. Reuse materials when possible. Recycle whenever possible. Rethink the materials you use and those you throw away. By thinking about what we're using and how to reduce the wast we produce, we can help create a cleaner, healthier environment.

Cut back your consumption. Water, food and air are consumed to support life. But we also consume much more than essentials, and far more than we should. There seems to be no end to the list of items and services we can’t live without. We must rethink what consumption is, and do our best to reduce it. The planet is being destroyed by the way societies function right now. It’s not just about recycling anymore; it’s about how to stop feeding the cycle altogether.

Animal agriculture emits more greenhouse gases than aircrafts, automobiles and trains combined. Forests are being cleared at alarming rates to feed grains to livestock that could feed the entire human race. Less trees means less impediments to CO2 being released into the air and thus more pollution. Animal waste is producing massive amounts of toxic levels of methane and ammonia, which leads to climate change as well as acid rain. Animal agriculture is also destroying our waterways and using up our valuable water supplies. Hormones, antibiotics, pesticides, fertilizers and other chemicals run off into rivers, lakes, streams and our drinkable water. These practices cause dead zones in the oceans, rivers and lakes. Animal farming is the leading cause of the catastrophic reduction of critical wildlife habitat, and the problem is escalating at a disturbing pace. Meat production is slated to double in another four decades. Remove or reduce meat, dairy and eggs from your diet.
