“…Similar to other U.S. specific studies with akin sample sizes [ 37 ], plastic pollution and oil spills where the top concerns across both surveys of our study. There have been major social-marketing campaigns around plastic pollution [ 37 , 38 ], ocean-based oil spills can have very visible and disastrous impacts on animals and local communities [ 39 ]–though evidence of singular environmental disasters’ influence is mixed [ 40 ]–and the ocean may still be seen as more wild, perhaps pristine, compared to the more engrained use and privatization of land [ 41 ]. While it is likely a combination of these and other factors, what is driving the slight difference may be worth further investigation.…”

Terrestrial and ocean ecosystems are increasingly under threat from an array of anthropogenic pressures. And while threats mount, how people view and value nature is changing. In the United States (U.S.) in particular, there is a shift away from viewing nature as something to ‘dominate,’ as evidenced in the decline in hunting. However, it is unclear if or how opinions around environmental issues and conservation need might differ when comparing ocean versus terrestrial ecosystems, especially given the prevalence and continued importance of wild capture fishing in the U.S. We employed two national parallel surveys, one focused on oceans, the other land, receiving responses from nearly every state in the U.S. (N = 1,973). While we found only slight, but statistically significant more concern for ocean habitats and animals over terrestrial ecosystems, this did not translate to increased willingness to monetarily support more ocean conservation actions. Using Random Forest models, we also found the best predictor of conservation need was feeling most impacted by environmental issues personally (self and/or community), regardless of ecosystem type. In fact, land versus sea (survey) had the lowest rank in the models, underscoring the importance of general nature-based interactions. Instead, the number of outdoor recreational activities was a highly ranked variable explaining the level of reported impact to self/community, with people who participate in 2 or more activities scoring higher levels of impact, on average. Notably, people who hunt and fish, versus only do one or the other, reported higher levels of impact and participated in more activities overall, providing a more nuanced finding regarding the nature ‘dominance hypothesis.’ Voting, not political affiliation, was also important in explaining responses, and governmental mechanisms to fund conservation were favored over voluntary. Overall, our results add to the strong existing literature that access and connection to nature is key, but uniquely broad connection may “float all boats,” especially when diversified.

“…Meanwhile, other pollutants such as sulfur oxide result in acid rain, which negatively affects crop yields. Apart from that, the numerous oil spills (≈1190 thousand tonnes) that have occurred between 1970 and 1990 have destroyed nearby terrestrial and aquatic ecosystems (Chen et al 2015 ; Farrow et al 2016 ; Lee and Jung 2015 ).…”

Fewer fossil fuel deposits, price volatility, and environmental concerns have intensified biofuel-based studies. Saccharification, gasification, and pyrolysis are some of the potential methods of producing carbohydrate-based fuels, while lipid extraction is the preferred method of producing biodiesel and green diesel. Over the years, multiple studies have attempted to identify an ideal catalyst as well as optimize the abovementioned methods to produce higher yields at a lower cost. Therefore, this present study comprehensively examined the factors affecting biodiesel stability. Firstly, isomerization, which is typically used to reduce unsaturated fatty acid content, was found to improve oxidative stability as well as maintain and improve cold flow properties. Meanwhile, polymers, surfactants, or small molecules with low melting points were found to improve the cold flow properties of biodiesel. Meanwhile, transesterification with an enzyme could be used to remove monoacylglycerols from oil feedstock. Furthermore, combining two natural antioxidants could potentially slow lipid oxidation if stainless steel, carbon steel, or aluminum are used as biodiesel storage materials. This present review also recommends combining green diesel and biodiesel to improve stability. Furthermore, green diesel can be co-produced at oil refineries that are more selective and have a limited supply of hydrogen. Lastly, next-generation farming should be examined to avoid competing interests in food and energy as well as to improve agricultural efficiency.

“…Some of the major concerns related to the environment are oil and oil-derived organic liquid spills, which may occur accidentally or deliberately by the oil industry, production, and transportation processes or human activities. − Oil and oil-derived organic liquids such as organic solvents, fuels, and fuel additives can cause not only energy loss but also has catastrophic impacts on marine life, aquatic ecosystems, soil, and groundwater when they are released into the environment. − Oil spills generally cover the surface of the water and prevent the transition of sunlight, which adversely affects marine species. Furthermore, another consequence of oil spillage is the permeation of oil-derived toxic organic liquids such as methyl tertiary butyl ether (MTBE) and BTEX (benzene, toluene, ethylbenzene, and xylene); these are known as the most common oil-based groundwater pollutants, affecting soil and groundwater by unwanted liquid leakage. , …”

Novel effective oil/organic solvent sorbents were designed and comprised entirely from polytetrahydrofuran (PTHF)-based networks in a two-step approach: (1) preparing PTHF-based macro-cross-linkers and (2) cross-linking of PTHF polymers using the prepared PTHF-based macro-cross-linkers. With this approach, different molecular weights of hydroxyfunctional PTHF polymers were turned into ethoxysilane-functional macro-cross-linkers by the modification of hydroxyl groups of PTHF polymers with 3-(triethoxysilyl)propyl isocyanate. Then, the prepared ethoxysilane-functional macro-cross-linkers were condensed with hydroxy-functional PTHF polymers to synthesize PTHF-based networks as oil/organic solvent sorbents. The synthesized PTHF-based sorbents demonstrated superior absorption properties in various oils and organic solvents such as dichloromethane, tetrahydrofuran, benzene, toluene, ethylbenzene, xylene, methyl tertiary butyl ether (MTBE), gasoline, and crude oil. The recovery of the sorbents after repeating the application for the absorption of dichloromethane and MTBE is essential, and they can be reused effectively for at least 50 days without any capacity loss. All the synthesized PTHF-based sorbents depicted high thermal stability. The characterization of the macro-cross-linkers and PTHF-based sorbents were determined by using 1 H, 13 C, and 29 Si nuclear magnetic resonances and Fourier transform infrared spectroscopies. Thermal characteristics of the sorbents were identified by thermogravimetric analysis and differential scanning calorimetry. Absorption kinetics of the sorbents were further analyzed using pseudo-kinetic models and an intraparticle diffusion model.
