If everyone in the world lived the way people do in the U.S., it would take five Earths to provide enough resources for everyone. #Lesson11#ClimateChange
Conserving ecosystems is often more cost-effective than human-made interventions. In the Maldives, building a sea wall for coastal protection cost about $2.2 billion. Even after 10 years of maintenance costs, it is still four times cheaper to preserve the natural reef. #Lesson11
An area of coastal ecosystems larger than New York City is destroyed every year, removing an important buffer from extreme weather for coastal communities and releasing carbon dioxide into the atmosphere. #Lesson11#Carbon
Eleven percent of the world’s population is currently vulnerable to climate change impacts such as droughts, floods, heat waves, extreme weather events and sea-level rise. #Lesson11#ClimateChange
Eleven percent of all global greenhouse gas emissions caused by humans are caused by deforestation — comparable to the emissions from all of the cars and trucks on the planet. #Lesson11
Before modern water heaters, homes would use a pipe loop called a water-back. It was connected to the stove and as water was heated, it would move through the pipe to a storage tank. #Lesson9#WaterHeating
In some densely populated areas of other countries (like Finland), homeowners receive their hot water through district heating, which distributes heat generated in a central location. #Lesson9#WaterHeating
