#Deforestation: "#Consumption patterns of G7 countries drive an average loss of 3.9 #trees per person per year. Some of the hotspots of deforestation embodied in international trade are also #biodiversity hotspots"
"#USA, #Japan, #Germany, #France, the #UK, and Italy, and several developing countries, such as #China and #India, have obtained net domestic forest gains. The net forest gains made in these countries were partially offset by importing embodied deforestation from elsewhere"
"Our analysis addresses two main questions: (i) Which #deforestation hotspots are driven by which consumer countries? and (ii) Which forest ecosystems, tropical rain forests or other forest types are the top targets of global supply chains?"
"Figure 2 shows the 15-year cumulative spatial #deforestation footprints of the #USA, #China, #Japan, #Germany (the world’s four largest economies), #Singapore (an Asian Tiger) and #Brazil (with the largest tropical rainforest area)."
".... However, these differences do not reflect the #responsibility of each country’s citizens regarding global #biodiversity threats and climate change because different tree types may have different environmental and ecological roles."
"Although the #USA, #Japan, #Germany, #Singapore, #China and #Russia increased their net forest imports from all biomes in 2015, compared with 2001, the imports of tropical #deforestation-related commodities increased significantly (Fig. 4)."
"Understanding global deforestation footprints is essential to create better regulatory policies and science-based interventions for protecting forests in various hotspots." #planning

"The #UnitedStates is experiencing an extreme teenage mental-health #crisis. From 2009 to 2021, the share of American high-school students who say they feel 'persistent feelings of sadness or hopelessness' rose from 26 percent to 44 percent"
"More than 1 in 4 girls reported that they had seriously contemplated attempting suicide during the pandemic, which was twice the rate of boys. Nearly half of LGBTQ teens said they had contemplated suicide during the pandemic, compared with 14 percent of their heterosexual peers"
"But the big picture is the same across all categories: Almost every measure of mental health is getting worse, for every teenage demographic, and it’s happening all across the country."
"Our results showed that (i) the #biodiversity loss per citizen shows large variations among countries, with higher values when per-capita income increases; (ii) the share of biodiversity losses due to GHG emissions in the ...
... #biodiversity#footprint increases with income; (iii) food consumption is the most important driver of biodiversity loss in most of the countries and regions, with a global average of 40%; ...
... (iv) more than 50% of the #biodiversity loss associated with consumption in developed economies occurs outside their territorial boundaries; and (v) the biodiversity footprint per dollar consumed is lower for wealthier countries.
"We find that, between 2009 and 2013, #tourism’s global #carbon#footprint has increased from 3.9 to 4.5 GtCO2e, four times more than previously estimated, accounting for about 8% of global greenhouse gas #emissions."
"The United States tops the carbon #footprint ranking (Fig. 1,top left) under both DBA (1,060 MtCO2e) and RBA (909 MtCO2e) accounting perspectives, followed by China (528/561 MtCO2e), Germany (305/329 MtCO2e) and India (268/240 MtCO2e)."
"The majority of these carbon #footprints are caused by domestic travel."
"Oxfam found that '13 out of the 15 #IMF loan programs negotiated during the second year of the #pandemic require new #austerity measures such as taxes on food and fuel or spending cuts that could put vital public services at risk.'"
"The Oxfam report notes that the conditions of a 2021 loan of $2.3 billion to #Kenya compelled the country to freeze public sector pay for three years, while mandating higher taxes on food and cooking gas"
"#Sudan has had to end fuel subsidies, a policy that has disproportionately affected the nearly 50% of the population that is impoverished."
"We found that in total 83% of total regional species loss (4747 species) is incurred due to land use devoted for domestic consumption whereas 17% due to export production (a total of 969 species)."
"Fig. 1c shows that imports into the USA&China embody highest species lost. It is interesting to see that even countries with smaller populations such as Japan, Germany, South Korea,...—all cause high biodiversity loss abroad owing to their high per capita consumption and import"
".... For example, total German food consumption was estimated to result in 46 species lost, of which 43 are from imported food items."
