Ecology and How to slove global warming

A tree planted for every T-shirt purchased. For every bottle of wine. For every swipe of a credit card. Trees planted by countries to meet global pledges and by companies to bolster their sustainability records.As the climate crisis deepens, businesses and consumers are joining nonprofit groups and governments in a global tree-planting boom. Last year saw billions of trees planted in scores of countries around the world.These efforts can be a triple win, providing livelihoods, absorbing and locking away planet-warming carbon dioxide, and improving the health of ecosystems. But when done poorly, the projects can worsen the very problems they were meant to solve. 

They get stressed and grow less well


Animals depend upon sound to find food, detect predators and communicate with one another. These species understandably suffer when loud motorways cut through their habitats. Some cope by singing more loudly, some change the timing of their calls to occur when fewer people are driving, others just move to quieter locales; What about plants ?

something about global population trends seems to send otherwise sensible people over the edge. According to the United Nations, the planet’s population is due to reach 8bn on November 15th. Alarm bells are clanging. Population pessimists have long predicted mass famine. Now they add prophecies of environmental disaster as a result of too many people. Others worry about the opposite problem: “population collapse due to low birth rates”, tweeted Elon Musk, the self-proclaimed “chief Twit”, “is a much bigger risk to civilisation than global warming.” In fact, looking at population change during the past decade suggests neither of these mutually contradictory divinations of doom will prove correct.
It took a dozen years (from 1998 to 2010) for the global population to grow from 6bn to 7bn. It has taken the same length of time to notch up the next billion. Against the backdrop of catastrophising, it is worth recalling what is behind this growth: longer lives, improvements in nutrition and public health; falls in infant mortality, disease and maternal deaths in childbirth. The world’s population carried on growing even in the teeth of the covid-19 pandemic, despite the virus killing—according to The Economist’s best estimates—between 16m and 28m people.
