Live and let live: Biodiversity
The effects of human action on the natural world are deeply harmful, and as our population increases and the search for economic growth continues, the threat will only increase. Damage to ecosystems across the world, and the resulting loss of biodiversity, has collected fewer headlines than other sustainability challenges, even though the biodiversity crisis is a direct risk to humankind.
Part of the problem is that it’s difficult to quantify due to the heterogeneity of ecosystems, making the correct response difficult to identify. Clearly, biodiversity loss is directly related to the climate emergency, and more companies, governments, and the public are recognizing this. For example, the protection of the ecosystems found in natural forests is a key solution to mitigating global warming. Extinction rates are multiple times higher than the historic rate, and approximately 1 million species are at threat out of a total of 8 million plant and animal species on earth. However, companies have consistently struggled to evaluate how their activities affect biodiversity, partly due to the exceptional complexity of the living systems that their value chains interact with.
Investments in biodiversity contribute directly to the full range of UN Sustainable Development Goals (SDGs). Conserving biodiversity and ecosystems preserves the ability of our planet to sustain our prosperity. Biodiversity finance combines conventional capital with financial incentives to fund sustainable biodiversity management. It can include private and public financial resources, and investments in commercial businesses that create positive biodiversity outcomes. However, most funding originates from public funds, including domestic public budgets, biodiversity-positive agricultural subsidies, and international transfers of public funds, and these activities haven’t been well communicated on a national scale. Moreover, without specific information on recipient-country expenditures and priorities, development partners have been unwilling to promise support to reach biodiversity management goals and objectives. Investors tend to lump the associated risks in with industries such as mining.
Some tools are currently being developed that compare how companies respond to material biodiversity risk, which should help investors understand how companies are mitigating “known unknown” risks, as well as compare how they balance economic returns with sustainable benefits. Many hope that such indicators will realize for biodiversity loss what the tools highlighting CO2 emission levels achieved for climate change (I cover CO2 earlier in this chapter). These indicators will need to identify any correlation between biodiversity and the success of the economy and allow investors to place an economic value on biodiversity.
See the forest for the trees: Deforestation
The EPA defines deforestation as the “permanent removal of standing forests.” However, such removal can occur for different reasons and has a variety of destructive consequences. Reports suggest that 80 percent of deforestation results from extensive cattle ranching and logging for materials and development. It has been happening for thousands of years, primarily since humans evolved from hunter-gatherer to agricultural-based societies and needed larger swathes of land to facilitate farming and housing. Modern requirements have converted this into an epidemic, leading to the loss of animal and plant species, due to their loss of habitat, as well as the following issues:
Healthy forests act as carbon sinks by absorbing carbon dioxide. Therefore, cutting down forests releases carbon into the atmosphere and reduces their ability to act as carbon sinks in future.
Trees also help manage the level of water in the atmosphere by regulating the water cycle. In deforested areas, there is less water in the air that is returned to the soil, resulting in dryer soil and an inability to grow crops. Furthermore, trees help the land retain water and topsoil, providing rich nutrients to sustain additional forest life, without which the soil erodes and washes away, causing farmers to move on and perpetuate the cycle.
The barren land left behind due to these unsustainable agricultural routines is more susceptible to flooding, especially in coastal regions. This also has an effect on seagrass meadows, a group of marine flowering plants, which are one of the world’s most productive ecosystems. They constitute an important CO2 sink, which is responsible for about 15 percent of the total carbon storage in the ocean.
As large amounts of forest are cleared away, indigenous communities, which rely on the forests to maintain their way of life, are also under threat. The governments of countries with native rainforests generally attempt to evict the indigenous tribes before the clearing occurs.
