Two Environment In The News Log Activities Each Log Entry Must Descri

Two Environment in the News log activities. Each log entry must describe an environmental event that has happened since June 1, 2015, is tied in some way to human effects on the environment, and is related to the ecosystem and population ecology. A good log entry describes the event, explains why the event caught your interest and is based on a strong reference source. The event can be something that humans did to the environment or something that the environment did to humans.

Introduction

Environmental events shaping the relationship between humans and nature have become focal points for ecological study and public consciousness. Since June 1, 2015, numerous significant events have underscored the dynamic interplay of ecosystem and population ecology affected by human actions or natural environmental shifts. This paper explores two such recent events, analyzing their ecological implications and human connections, supported by credible sources.

Event 1: Amazon Rainforest Deforestation and Its Impact on Biodiversity

In August 2019, reports documented a significant surge in deforestation within the Amazon rainforest, driven primarily by illegal logging, agricultural expansion, and infrastructure development (NASA, 2019). The Amazon, known as the "lungs of the Earth," plays a critical role in global carbon sequestration and maintains biodiversity hotspots vital for ecosystem stability (Lovejoy & Nobre, 2018). The rate of deforestation increased markedly during this period, with estimates suggesting an area of approximately 3,700 square kilometers lost in the year alone (INPE, 2019).

This event captivated my interest because the Amazon's health is directly related to global climate regulation and biodiversity conservation. Deforestation affects species richness and disrupts ecological functions, leading to habitat fragmentation and increased extinction risks (Foley et al., 2018). The human-driven causes underscored the importance of sustainable land-use practices and policy enforcement efforts. The implications extend to climate feedback loops, as reduced forest cover decreases carbon uptake, exacerbating global warming.

From a population ecology perspective, the loss of habitat impacts native species’ distributions and population sizes, leading to potential local extinctions and altered predator-prey dynamics (Malhi & Wright, 2016). The event underscores the urgent need for conservation strategies that mitigate human impact and promote ecological resilience.

Event 2: Ocean Plastics Pollution and its Effect on Marine Life

In July 2016, the creation and accumulation of microplastics in the Pacific Ocean's gyres reached alarming levels, posing severe threats to marine ecosystems (Eriksen et al., 2014). Microplastics, originating from degraded larger plastic debris and microbeads from personal care products, are ingested by a wide range of marine organisms, from plankton to seabirds (Wright et al., 2013).

This event attracted my attention because it vividly illustrates the intersection of human material consumption and environmental deterioration. The persistent nature of plastics in marine environments, coupled with their bioaccumulation through food webs, exemplifies ecosystem disruption and population ecology concerns (Galloway et al., 2017). The ingestion of microplastics can cause physical injuries, reduce reproductive success, and introduce toxic chemicals into marine organisms, which can then transfer up the food chain to humans.

Natural environmental processes also influence microplastic distribution, with ocean currents spreading debris globally. This natural dispersion underscores the importance of understanding ecological connectivity and implementing human-led waste management reforms. The event highlights how human behaviors, such as plastic consumption and improper waste disposal, directly impact marine biodiversity and ecosystem stability.

Conclusion

Both the Amazon deforestation and marine plastic pollution exemplify critical environmental phenomena tied to human influence, with profound effects on ecosystem health and population dynamics. These events underscore the necessity for integrated approaches combining ecological research, public awareness, and policy action to mitigate human impacts and preserve ecological integrity.
