Tigers in India

March 17, 2025 By EarthWise Leave a Comment

The Anthropocene is the term that describes the current era in Earth’s history when human activities are having a significant impact on the planet.  It is an epoch filled with species extinction and species attrition in both numbers and range.  The population of large carnivores are among the most affected species and recovering these animals that play important roles in ecosystems is a formidable challenge.

Tigers in Asia are a prime example of extirpation – removal of a species from a specific area.  They have been eliminated in more than 90% of their historic Asian range over the past century.  A new study, published in Science has found that tigers in India are making a comeback.

India’s National Tiger Conservation Authority estimates that between 2010 and 2022, India’s tiger population grew from 1,706 to 3,682.  Tigers are thriving not only on protected lands but also near some human communities.

Tigers are gone from poorer areas where poaching was prevalent and from areas affected by the violent conflict associated with India’s Maoist rebellion.  On the other hand, the big cats can be found near some prosperous communities where poaching is rare.  Farmers keep cattle in enclosures to protect them from tigers.  

The success in protecting tigers in India could provide some insights for Europe where wolves are making a comeback, and perhaps even in the American West where the resurgence of wolf populations is triggering a violent backlash.

Large predators can survive in the modern world with creative thinking and willingness to find a balance between protection and coexistence.

How Environmentally Friendly Are We? | Earth Wise

January 27, 2020 By EarthWise 1 Comment

Many of us are very concerned about the environment and want to try to do the right things as we go about our daily lives.  New research from the University of Gothenburg shows that we tend to overestimate just how much we are actually doing.

A study of over 4,000 people in United States, England, India, and Sweden revealed that most people are convinced that they act more environmentally friendly than the average person.  Their actions might include buying eco-labelled products, saving household energy, recycling, driving a hybrid or electric car, and reducing purchases of plastic bags.  Participants in the survey rated themselves as more environmentally active than other people, including both unknown people as well as their own friends.

The results are in keeping with a general tendency people have to overestimate their own abilities.  Studies over the years have shown that most people consider themselves, for example, to be more honest, more creative, and better drivers than others.  This sort of over-optimism apparently also applies to environmentally friendly behaviors.

The data from the survey revealed that the participants were more likely to overestimate their engagement in activities they perform often and draw the faulty conclusion that the things they do often, they in fact do more often than others.

A consequence of thinking that you are more environmentally friendly than other people is that it can reduce the motivation to act environmentally friendly in the future.  In fact, when we think we are more environmentally friendly than others, we actually end up becoming less environmentally friendly.

Logically speaking, the majority of people cannot be more environmentally friendly than the average person.  We are not living in Lake Wobegone where all children are above average.

The North Atlantic island of Bermuda is a popular tourist attraction with its pink sand beaches, turquoise water, and pastel-colored cottages with white limestone roofs.   The stepped white roofs are not just picturesque, they are highly functional.
